Description

TECHNICAL FIELD

The present invention relates to communications technologies, and in particular, to a base station provisioning method and a base station provisioning system.

BACKGROUND

To meet a service development requirement of an operator, a quantity of base stations keeps increasing, and growing costs of base station provisioning draws more attention from the operator. Reducing skills of base station provisioning personnel and accelerating the base station provisioning are important factors for reducing the costs of the base station provisioning.
In the prior art, when a base station is provisioned by an operator, a manner of a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) may be used to implement fast and cost-effective base station provisioning. The base station first broadcasts a DHCP request, and a DHCP server allocates an IP address to the base station after the broadcast is received. After acquiring the IP address, the base station may automatically connect to the server and automatically complete, according to a preconfigured task, operations such as base station parameter configuration.
However, because a broadcast storm may be caused after a DHCP relay function is enabled, efficiency of base station provisioning is low.

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Technologies described in this specification may be applied to various communications systems, for example, current 2G and 3G communications systems and a next-generation communications system, for example, a Global System for Mobile Communications (GSM, Global System for Mobile communications), a Code Division Multiple Access (CDMA, Code Division Multiple Access) system, a Time Division Multiple Access (TDMA, Time Division Multiple Access) system, a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access Wireless) system, a Frequency Division Multiple Access (FDMA, Frequency Division Multiple Addressing) system, an Orthogonal Frequency-Division Multiple Access (OFDMA, Orthogonal Frequency-Division Multiple Access) system, a single-carrier FDMA (SC-FDMA) system, a General Packet Radio Service (GPRS, General Packet Radio Service) system, a Long Term Evolution (LTE, Long Term Evolution) system, and other communications systems.
A base station in the present application (for example, an access point) may be a base station (BTS, Base Transceiver Station) in GSM or the CDMA, or may be a base station (NodeB) in WCDMA, or may be an evolved NodeB (eNB or e-NodeB, evolved Node B) in LTE, which is not limited in this application.
FIG. 1 is a flowchart of an embodiment of a base station provisioning method according to the present invention. As shown in FIG. 1, the method in this embodiment may include:

Step 101. A first base station sends an Internet Protocol IP query request to a router, so that the router sends the IP query request to a server, where the IP query request includes identification information of the first base station and a temporary IP address of the first base station.

Step 102. The first base station receives an IP query request response that is forwarded by the router to the first base station according to the temporary IP address, where the IP query request response carries a formal IP address that is allocated by the server to the first base station according to the identification information of the first base station.
Step 103. The first base station sends a provisioning request to the router, so that the router sends the provisioning request to the server, where the provisioning request carries the formal IP address.
Step 104. The first base station receives a provisioning response that is forwarded by the router to the first base station according to the formal IP, where the provisioning response carries a base station start parameter that is configured by the server for the first base station.
In this embodiment of the present invention, one router may be connected to multiple base stations, and one server may be connected to multiple routers. Information sent by a base station to a server needs to be first sent to a router and then be forwarded by the router to the server. Similarly, information sent by the server to the base station needs to be first sent to the router, and be forwarded by the router to the base station.
The first base station involved in this embodiment of the present invention may be any base station in a network. Identification information of the base station may be used to uniquely identify the base station in the network, for example, the identification information may be an electronic serial number (Electronic Serial Number, ESN) of the base station, or other identification information, which is not limited in the present invention.
One temporary IP address or multiple IP addresses may be set in one network segment (including one router, and multiple base stations connected to the router). Generally, one temporary IP address may be set in one network segment to reduce IP address resources. The temporary IP address may be stored in a device with a storage function, such as a USB flash drive. By using a network interface, a serial interface, a fiber interface on a board of a base station, or another communications interface, the base station may be connected to and communicate with a device that has a storage function, and read the temporary IP address that is in the network segment and stored on the device that has the storage function. It should be noted that the present invention sets no specific limit on how to store the temporary IP address and how a base station acquires the temporary IP address.
After receiving the IP query request sent by the first base station, the server may allocate, according to the identification information of the first base station, a corresponding formal IP address to the first base station, and send the formal IP address. The server stores information such as formal IP addresses, subnet masks, and next-hop routes that are of all base stations in all networks. After acquiring the formal IP address, the first base station may use the formal IP address to send the provisioning request to the server. After receiving the provisioning request, the server sends a configuration parameter needed for provisioning the base station (different parameters need to be configured for provisioning of base stations of different types, for example, the parameters may include a base station name, a sector number, a location area, a routing area, and a cell type, and details are not described again in the present invention) to the base station, and the first base station may perform base station provisioning according to the parameter sent by the server.
Further, before sending the IP query request to the router, the first base station may further discover the router, and a specific process is: the first base station receives a first Address Resolution Protocol ARP request, where the first ARP request carries an IP address and a Media Access Control MAC address that are of the router. The first base station determines, according to the IP address of the router, a network segment in which the first base station is located. The first base station may acquire, according to the network segment, a temporary IP address corresponding to the network segment. Different temporary IP addresses may be planned in different network segments; therefore, according to the foregoing steps, it may be ensured that the base station acquires a correct temporary IP address.
Further, after the first base station receives the first ARP request sent by the router, the router may further discover the base station, and a specific process is: the first base station may further send a gratuitous ARP response to the router according to the IP address of the router, where the gratuitous ARP response carries a MAC address of the first base station.
According to the foregoing steps, the base station can learn the IP address and MAC address that are of the router, and the router can also learn the temporary IP address and the MAC address that are of the base station; therefore, normal communication between the router and the base station is ensured.
Further, when the router is attacked, an ARP entry error may occur, or after a network device changes, an ARP entry of the router may not be updated in time. In either case, the server may send an allocated formal IP address to another second base station, except the first base station, in the network. For the purpose of resolving this problem, the IP query request response may further include: identification information of another second base station, except the first base station, in the network segment in which the first base station is located, and a formal IP address corresponding to the another second base station. After the first base station sends the IP query request to the router, if the first base station does not receive the IP query request response within a set time, the first base station sends a gratuitous ARP request to the router, so that the router updates a correspondence between the temporary IP address and the MAC address that are of the first base station. The first base station resends the IP query request to the router, so that the router sends the IP query request to the server.
If multiple first base stations are involved, that is, in an implementation scenario in which multiple base stations are being simultaneously provisioned, a case of "IP preemption" may occur, and base station provisioning is affected. In this embodiment, if the first base station and the second base station are being simultaneously provisioned, and an ARP entry in the router is tampered, for example, the entry is tampered from "the temporary IP address is corresponding to the MAC address of the first base station" to "the temporary IP address is corresponding to the MAC address of the second base station", the router forwards the IP query request response received from the server to the second base station. In this case, automatic provisioning may be implemented after the second base station receives the IP query request (the IP query request carries formal IP addresses of all base stations that are not provisioned in the network segment); however, the first base station cannot receive the IP query request response. At this time, the first base station may send the gratuitous ARP request, and a source IP address and a destination IP address that are carried in the ARP request are temporary IP addresses of the first base station, where a source MAC address is the MAC address of the first base station, and a destination MAC address is a broadcast address, so as to instruct the router to update the ARP entry. After updating the ARP entry, the router may forward the IP query request response to the first base station.
Optionally, before sending the IP query request to the router, the first base station may first determine whether the temporary IP address is being occupied by another base station. Specifically, the first base station may send a second ARP request, where a destination address of the second ARP request is the temporary IP address. If the first base station receives the ARP response to the ARP request, it indicates that the temporary IP address is being occupied by the another base station. The first base station needs to wait until the another base station that occupies the temporary IP address releases the temporary IP address, and then the first base station may occupy the temporary IP address. If the first base station resends the ARP request after a set first time, until the ARP response is not received by the first base station within a set second time, which indicates that at this time, no other base station is occupying the temporary IP address, and then the first base station may occupy the temporary IP address.
According to the base station provisioning method provided in the present application, a base station may send an IP query request to a server by using a temporary IP address and a router, so as to request the server to allocate a formal IP address for the base station; after obtaining the formal IP address, the base station may request, by using the formal IP address and the router, the server to allocate a parameter related to the base station provisioning, which improves efficiency of the base station provisioning and reduces costs of the base station provisioning.
FIG. 2 is a flowchart of another embodiment of a base station provisioning method according to the present invention. As shown in FIG. 2, the method in this embodiment may include:

Step 201. A router receives an Internet Protocol IP query request sent by a first base station, and sends the IP query request to a server, where the IP query request includes identification information of the first base station and a temporary IP address of the first base station.

Step 202. The router forwards an IP query request response to the first base station according to the temporary IP address, where the IP query request response carries a formal IP address that is allocated by the server to the first base station according to the identification information of the first base station.
Step 203. The router receives a provisioning request sent by the first base station, and forwards the provisioning request to the server, where the provisioning request carries the formal IP address.
Step 204. The router forwards a provisioning response to the first base station according to the formal IP address, where the provisioning response carries a base station start parameter configured by the server for the first base station.
In this embodiment of the present invention, one router may be connected to multiple base stations, and one server may be connected to multiple routers. Information sent by a base station to a server needs to be first sent to a router and then be forwarded by the router to the server. Similarly, information sent by the server to the base station needs to be first sent to the router, and be forwarded by the router to the base station.
The first base station involved in this embodiment of the present invention may be any base station in a network. Identification information of the base station may be used to uniquely identify the base station in the network, for example, the identification information may be an electronic serial number (Electronic Serial Number, ESN) of the base station, or other identification information, which is not limited in the present invention.
One temporary IP address or multiple IP addresses may be set in one network segment (including one router, and multiple base stations connected to the router). Generally, one temporary IP address may be set in one network segment to reduce an IP address resource. The temporary IP address may be stored in a device with a storage function, such as a USB flash drive. By using a network interface, a serial interface, a fiber interface on a board of a base station, or another communications interface, the base station may be connected to and perform communication with a device that has a storage function, and read the temporary IP address that is in the network segment and stored on the device that has the storage function. It should be noted that the present invention sets no specific limit on how to store the temporary IP address and how a base station acquires the temporary IP address.
After receiving the IP query request sent by the first base station, the server may allocate, according to the identification information of the first base station, a corresponding formal IP address to the first base station, and send the formal IP address. The server stores information such as formal IP addresses, subnet masks, and next-hop routes that are of all base stations in all networks. After acquiring the formal IP address, the first base station may use the formal IP address to send the provisioning request to the server. After receiving the provisioning request, the server sends a configuration parameter needed for provisioning the base station (different parameters need to be configured for provisioning of base stations of different types, for example, the parameters may include a base station name, a sector number, a location area, a routing area, and a cell type, and details are not described again in the present invention) to the base station, and the first base station may perform base station provisioning according to the parameter sent by the server.
Further, before the router receives the IP query request sent by the first base station, the first base station may further discover the router, and a specific process is: the router sends a first Address Resolution Protocol ARP request to the first base station, where the first ARP request carries an IP address and a Media Access Control MAC address that are of the router, so that the router determines, according to the IP address of the router, a network segment in which the base station is located, and acquire, according to the network segment, the temporary IP address corresponding to the network segment.
Further, after the router sends the first ARP request to the first base station, the router may further discover the base station, and a specific process is: the router receives a gratuitous ARP response that is sent by the first base station according to the IP address of the router, where the gratuitous ARP response carries a MAC address of the first base station.
According to the foregoing steps, the base station can learn the IP address and MAC address that are of the router, and the router can also learn the temporary IP address and the MAC address that are of the base station; therefore, normal communication between the router and the base station is ensured.
Further, when the router is attacked, an ARP entry error may occur, or after a network device changes, an ARP entry of the router may not be updated in time. In either case, the server may send an allocated formal IP address to another second base station, except the first base station, in the network. For the purpose of resolving this problem, the IP query request response may further include: identification information of another second base station, except the first base station, in the network segment in which the first base station is located, and a formal IP address corresponding to the another second base station. After the first base station sends the IP query request to the router, if the first base station does not receive the IP query request response within a set time, the first base station sends a gratuitous ARP request to the router, so that the router updates a correspondence between the temporary IP address and the MAC address that are of the first base station. The first base station resends the IP query request to the router, so that the router sends the IP query request to the server.
If multiple first base stations are involved, that is, in an implementation scenario in which multiple base stations are being simultaneously provisioned, a case of "IP preemption" may occur, and base station provisioning is affected. In this embodiment, if the first base station and the second base station are being simultaneously provisioned, and an ARP entry in the router is tampered, for example, the entry is tampered from "the temporary IP address is corresponding to the MAC address of the first base station" to "the temporary IP address is corresponding to the MAC address of the second base station", the router forwards the IP query request response received from the server to the second base station. In this case, automatic provisioning may be implemented after the second base station receives the IP query request (the IP query request carries formal IP addresses of all base stations that are not provisioned in the network segment); however, the first base station cannot receive the IP query request response. At this time, the first base station may send the gratuitous ARP request, and a source IP address and a destination IP address that are carried in the ARP request are temporary IP addresses of the first base station, where a source MAC address is the MAC address of the first base station, and a destination MAC address is a broadcast address, so as to instruct the router to update the ARP entry. After updating the ARP entry, the router may forward the IP query request response to the first base station.
According to the base station provisioning method provided in the present application, a base station may send an IP query request to a server by using a temporary IP address and a router, so as to request the server to allocate a formal IP address for the base station; after obtaining the formal IP address, the base station may request, by using the formal IP address and the router, the server to allocate a parameter related to the base station provisioning, which improves efficiency of the base station provisioning and reduces costs of the base station provisioning.
FIG. 3 is a flowchart of still another embodiment of a base station provisioning method according to the present invention. As shown in FIG. 3, the method in this embodiment may include:

Step 301. A server receives an Internet Protocol IP query request that is received by a router from a first base station and forwarded to the server, where the IP query request includes identification information of the first base station and a temporary IP address of the first base station.

Step 302. The server sends an IP query request response to the router, so that the router forwards the IP query request response to the first base station, where the IP query request response carries a formal IP address allocated by the server to the first base station according to the identification information of the first base station.
Step 303. The server receives a provisioning request that is received by the router from the first base station and forwarded to the server, where the provisioning request carries the formal IP address.
Step 304. The server sends a provisioning response to the router, so that the router forwards the provisioning response, where the provisioning response carries a base station start parameter configured by the server for the first base station.
Further, the IP query request response further includes: identification information of another second base station, except the first base station, in the network segment in which the first base station is located, and a formal IP address corresponding to the another second base station.
In this embodiment of the present invention, one router may be connected to multiple base stations, and one server may be connected to multiple routers. Information sent by a base station to a server needs to be first sent to a router and then be forwarded by the router to the server. Similarly, information sent by the server to the base station needs to be first sent to the router, and be forwarded by the router to the base station.
The first base station involved in this embodiment of the present invention may be any base station in a network. Identification information of the base station may be used to uniquely identify the base station in the network, for example, the identification information may be an electronic serial number (Electronic Serial Number, ESN) of the base station, or other identification information, which is not limited in the present invention.
One temporary IP address or multiple IP addresses may be set in one network segment (including one router, and multiple base stations connected to the router). Generally, one temporary IP address may be set in one network segment to reduce an IP address resource. The temporary IP address may be stored in a device with a storage function, such as a USB flash drive. By using a network interface, a serial interface, a fiber interface on a board of a base station, or another communications interface, the base station may be connected to and perform communication with a device that has a storage function, and read the temporary IP address that is in the network segment and stored on the device that has the storage function. It should be noted that the present invention sets no specific limit on how to store the temporary IP address and how a base station acquires the temporary IP address.
After receiving the IP query request sent by the first base station, the server may allocate, according to the identification information of the first base station, a corresponding formal IP address to the first base station, and send the formal IP address. The server stores information such as formal IP addresses, subnet masks, and next-hop routes that are of all base stations in all networks. After acquiring the formal IP address, the first base station may use the formal IP address to send the provisioning request to the server. After receiving the provisioning request, the server sends a configuration parameter needed for provisioning the base station (different parameters need to be configured for provisioning of base stations of different types, for example, the parameters may include a base station name, a sector number, a location area, a routing area, and a cell type, and details are not described again in the present invention) to the base station, and the first base station may perform base station provisioning according to the parameter sent by the server.
According to the base station provisioning method provided in the present application, a base station may send an IP query request to a server by using a temporary IP address and a router, so as to request the server to allocate a formal IP address for the base station; after obtaining the formal IP address, the base station may request, by using the formal IP address and the router, the server to allocate a parameter related to the base station provisioning, which improves efficiency of the base station provisioning and reduces a costs of the base station provisioning.
FIG. 4 is a signaling diagram of an embodiment of a base station provisioning system according to the present invention. As shown in FIG. 4, the system includes the following steps:

Step 4001. A router sends a first ARP request to a first base station.

The router sends an ARP request, and then the first base station may learn, according to the ARP request, an IP address and a MAC address that are of the router.
Step 4002. The first base station determines a network segment.
The first base station may learn, according to the IP address of the router, a network segment in which the first base station is located.
Step 4003. The first base station sends a gratuitous ARP response to the router.
This step is used by the base station to register a MAC address with the router. By performing this step, the router may learn the MAC address of the base station.
Step 4004. The first base station sends a second ARP request, and waits for a response.
This step is used by the first base station to determine, before occupying a temporary IP address, whether the temporary IP address is being occupied by another base station. If a response to the second ARP request is received, it indicates that the temporary IP address is being occupied by the another base station. The first base station needs to wait until the base station that occupies the temporary IP address releases the temporary IP address, and then the first base station may occupy the temporary IP address.
Step 4005. The first base station selects the temporary IP address, that is, the first base station occupies the temporary IP address.
Step 4006. The first base station sends an IP query request to a server.
This step is used by the first base station to query, from the server, a formal IP address of the first base station, where the IP query request carries the temporary IP address.
Step 4007. The second base station preempts an IP.
If the second base station is being provisioned, and the IP preemption occurs in the second base station, an ARP entry of the router is tampered, for example, the ARP entry is tampered from "the temporary IP address is corresponding to the MAC address of the first base station" to "the temporary IP address is corresponding to the MAC address of the second base station".
Step 4008. The server sends an IP query response.
After receiving the IP query request, the server sends the IP query response to the router, and because the ARP entry of the router is tampered, the router sends the IP query response to the second base station, and the first base station cannot receive the IP query response. Because the IP query response carries formal IP addresses of all base stations that are not provisioned, all second base stations learn a formal IP address of the second base station.
Step 4009. The second base station sends a provisioning request, where the provisioning request carries the formal IP address of the second base station.
Step 4010. The server sends a provisioning response to the second base station to implement provisioning of the second base station.
Step 4011. The first base station sends the gratuitous ARP request to the router.
This step is used by the first base station to instruct the router to update the ARP entry of the first base station.
Step 4012. The router updates the ARP entry.
Step 4013. The first base station resends the IP query request to the server.
Step 4014. The server sends an IP query request response to the first base station.
Because the ARP entry of the router is updated, the first base station receives the IP query request response, and learns the formal IP address of the first base station according to the IP query request response.
Step 4015. The first base station sends a provisioning request to the server, where the provisioning request carries the formal IP address of the first base station.
Step 4016. The server sends a provisioning response to the first base station, where the provisioning response carries a configuration parameter needed for provisioning the first base station, so as to implement the provisioning of the first base station.
The foregoing steps 4001 to 4003 are corresponding to a process in which the first base station and the router discover each other. The first base station acquires the temporary IP address in step 4005. Optionally, the first base station determines, in step 4004, whether the temporary IP address is being occupied by the another base station. Step 4006 and step 4014 are a process in which the first base station acquires the formal IP address. Optionally, if the temporary IP address is preempted by the second base station, as shown in step 4007, the second base station may be provisioned by performing steps 4008 to 4010; however, the first base station cannot acquire the formal IP address, and then the first base station needs to re-acquire the formal IP address by performing steps 4011 to 4013, steps 4015 to 4016 need to be performed to implement provisioning of the base station.
According to the base station provisioning method provided in the present application, a base station may send an IP query request to a server by using a temporary IP address and a router, so as to request the server to allocate a formal IP address for the base station; after obtaining the formal IP address, the base station may request, by using the formal IP address and the router, the server to allocate a parameter related to the base station provisioning, which improves efficiency of the base station provisioning and reduces costs of the base station provisioning.
